Bulldog Painting in Progress - still!

Slowly, but surely, I'm making progress. I *so* feel like this dog looks - EXHAUSTED. In fact, I've definitely decided that's the title of the painting. The nose and mouth are have been the hardest. I'm trying not to pick at it too much, but I see an area I need to darken a bit. That's one great thing about posting these in progress photos...I see my "problem spots". Of course, I know you all like seeing the in progress as well. Back to work...
